Dispensing device for dispensing active substance fluids into the flushing liquid inside a toilet bowl

ABSTRACT

The invention relates to a dispensing device for dispensing active substance fluid into the flushing liquid inside a toilet bowl. The dispensing device comprises a holder ( 1 ) that can be suspended-on the edge of the toilet bowl and comprises at least two reservoirs ( 2, 3 ), which are separate from one another, are provided inside the holder ( 1 ), and which each accommodate an active substance fluid. Each reservoir ( 2, 3 ) has its own discharge opening ( 4 ) via which the respective active substance fluid can be dispensed into the flushing liquid. The inventive dispensing device is characterized in that flushing liquid is not permitted to enter the interior of the reservoirs ( 2, 3 ), and the discharge openings ( 4 ) of the reservoirs ( 2, 3 ) are arranged so that only active substance fluid is discharged and a partial quantity of the active substance fluid is dispensed from each of the reservoirs ( 2,3 ) into the flushing liquid during each flushing.

The invention relates to a dispensing device for dispensing activesubstance fluids into the flushing liquid in a toilet bowl, with thefeatures of the introductory part of claim 1.

[0001] The term active substance fluid means flowable, thus liquid toviscous, in a given case gel-like or even pasty or granular or otherwisepourable, active substance preparations with cleansing, disinfecting,deodorising, bleaching or similar action (particularly described in DE199 30 362 A1, which is not prior published, as well as in EP 0 775 741A1 and EP 0 960 984 A2).

[0002] Dispensing devices of the usual kind are known in various formsunder the catchword “WC baskets”. In the first instance, dispensingdevices are known for a single active substance fluid. The activesubstance fluid is there disposed in a storage container, which isfixedly arranged or exchangeably inserted in a holder, with an outletopening arranged at the base side when the storage container is mountedat the holder.

[0003] In a first known dispensing device for a single active substancefluid the active substance fluid is delivered by way of an actuatingelement (for example, from an open-pore foam material) saturatedtherewith and loadable by the flushing liquid (EP 785 315 A1). Here theoutlet opening of the storage container is for the most part closedafter the pushing out of a closure part of the storage container by asealing element arranged at the holder in stationary position, so that aflow path with only a small cross-section is available for the seepingout of the active substance fluid. The device functions with utilisationof the capillary effect of the open-pore foam material. A similarconstruction with a rib plate serving for the distribution is alsoknown.

[0004] In the case of both variants it has on occasions felt not to beoptimal that the outlet opening is in principle permanently open, sothat active substance fluid can continue to seep out over longer termnon-use of the toilet bowl.

[0005] Another dispensing device for a single active substance fluid (DE299 02 066 U1) has at the storage container a sealing element whichoperates in valve-like manner and which normally adopts a positive,closed closure setting in which the outlet opening is closed. Thishappens under the action of the gravitational force of a valve ballacting as a sealing element. This sealing element can be displacedagainst the biasing force into a release setting slightly freeing theoutlet opening. An actuating element constructed as a rocker andpivotably mounted on a pivot axis at the holder serves for this purpose.The actuating element has at one side of the axis a loading regionhaving a pan-shaped receptacle for flushing liquid. The arm of theactuating element lying on the other side of the axis bears from belowagainst the sealing element. If the flushing liquid impinges on theinfluencing region, then the actuating element is lifted off the valveseat at the outlet opening by way of the actuating element and slightlyfrees the outlet opening. The active substance fluid can seep past thesealing element out of the outlet opening into the current of flushingliquid flowing by or is entrained by the flushing liquid. A dispensingdevice similar to the previously explained dispensing device is knownfrom DE 199 30 362 A1 already mentioned further above but not priorpublished, the device having, however, as actuating element a single-armlever which is pivotably connected at one end with the holder and atwhich the sealing element is arranged between the end pivotablyconnected with the holder and the loading region. This constructioncorresponds, in particular, with a storage container exchangeablyarranged at the holder.

[0006] In the case of use of the previously explained dispensing devicesof the usual kind all components entering the flushing liquid of thetoilet bowl have to be included in common in the active substance fluid.However, many active substance components cannot be realised in a formstable in conjunctive storage. Accordingly, a multi-chamber dispensingdevice has already been proposed (EP 0 960 984 A2). This knowndispensing device serves for dispensing at least two different orequally solid, gel-like, pasty or liquid media in liquid or aqueous forminto a toilet bowl. A container, which has at least two independentchambers arranged adjacent to one another for storage of the media, isdisposed at a holder able to be suspended at the edge of the toiletbowl. Each chamber has a dispensing device with a dispensing tubeletwhich exits into the environment by one free end thereof via the base ofthe container and is surrounded at the other free end thereof influid-guiding manner by a cover. The two chambers of the container canbe filled via slot-like passages of a cover part by flushing waterflowing over, which then issues into the toilet bowl in the manner of asiphon or overflow by way of the dispensing tubelet with entrainment ofthe respective active substance. The separation of the chambers in thecontainer has the advantage that different media can be used which wouldotherwise adversely influence one another in their desired effect in thecase of common storage in only one chamber. In addition, the consistencyof the media can be different in the different chambers.

[0007] In the dispensing device explained above the principle offunctioning of known “WC baskets” is utilised, according to which theflushing water flowing over from above flows into the chamberscontaining the active substance fluid, detaches parts of the activesubstance material and, with entrainment thereof, flows back out of thechambers. In that case the problem exists that a substantial liquidlevel is left behind in the chambers by the siphon action effected here.The action of the flushing liquid on the active substance fluid in therespective chambers thus continues even when the flushing process haslong been concluded. The consumption of active substance fluid cannot,in practice, be controlled in optimum manner.

[0008] There is also known a double-chamber dispensing device for likeor different gel-like active substance fluids (WO 92/20876 A1), in whichthe outlet openings are executed as perforations in the storagecontainers at the base and are permanently open. Due to the viscosityand surface tension of the gel, this normally cannot exit by itselfunder gravitational force. Partial quantities of the active substancefluids can be discharged only by flushing liquid which runs over andwhich enters from below into the outlet openings and etches to somedegree the gel near the outlet openings. In this double-chamber systemit is thus similarly the case that the outlet openings are basicallypermanently open, so that also with longer-term non-use of the toiletbowl the active substance fluids can either seep out or solidify underthe influence of the ambient atmosphere and thereafter are no longeractivatable.

[0009] The teaching is based on the problem of optimising the knowndispensing device explained in the foregoing, for dispensing activesubstance fluids from at least two mutually separate storage containers,with respect to possibility of control of the dispensing of the activesubstance fluids.

[0010] The set problem demonstrated in the foregoing is solved, in thecase of a dispensing device with the features of the introductory partof claim 1, by the features of the characterising part of claim 1.According to the invention the storage containers are protected againstthe entry of flushing liquid into the interior thereof and only activesubstance fluid issues from the outlet openings of the storagecontainers. This is realised in the manner that with each flushingprocess the dispensing of a partial quantity of the active substancefluid into the flushing water takes place from each storage container.

[0011] In the sense of solution of the set problem defined in theforegoing an embodiment of the dispensing device, which is in accordancewith the invention, according to claim 16 is particularly advantageous.A positive closure of the outlet openings is advantageous in thisconcept particularly for the purpose of defined dimensioning of thepartial quantities and for the purpose of protection of the activesubstance fluids in the storage containers in the case of non-use in thelonger term.

[0012] The technical principles of dispensing devices for a singleactive substance fluid, which are known in the state of the art andwhich have already been comprehensively explained further above, areavailable for realisation of the construction according to theinvention. In particular, reference must be made for this purpose to thestate of the art discussed further above.

[0013] Preferred embodiments and developments of the teaching are thesubject of the subclaims.

[0014] Moreover, a preferred embodiment of the invention is explained inmore detail by reference to the drawing, in which:

[0015]FIG. 1 shows a preferred embodiment of a dispensing deviceaccording to the invention, in a plan view,

[0016]FIG. 2 shows a section through the device of FIG. 1 along the lineII-II and

[0017]FIG. 3 shows a section through the device of FIG. 2 along the lineIII-III.

[0018] The dispensing device illustrated in the drawings serves fordispensing of at least two active substance fluids into the flushingliquid which is flushed into a toilet bowl. With regard to what is to beunderstood in the sense of the teaching as active substance fluid, thishas already been defined in the general part of the description andreference may be made thereto.

[0019] Such a dispensing device comprises, in the first instance, aholder 1 which can be suspended at the edge of the toilet bowl and atleast two mutually separate storage containers 2, 3, which are providedin the holder 1, each for a respective active substance fluid. Theactive substance fluids can be corresponding, different, mutuallycompatible or mutually incompatible active substance fluids. Two storagecontainers for two active substance fluids or more storage containersfor more active substance fluids can be given.

[0020] According to the invention suitable active substance fluids are,for example, aromatic phases, particularly perfumed aromatic phases.Such aromatic phases usually contain at least one aromatic, preferablyperfume oil, at least one surfactant or emulsifier and water as well as,in a given case, further ingredients such as preservatives, thickeners,sequestering agents, colorants, further surfactants or emulsifiers,stabilisers, descalers, etc.

[0021] According to the invention equally suitable as active substancefluids are bleaching phases, particularly bleaching phases containingchlorine, for example bleaching phases based on hypochlorite, whereinthe bleaching phases can usually contain, apart from the actualbleaching agent and water, optionally further ingredients such asthickeners, surfactants or emulsifiers, neutralisers, colorants,aromatics, etc.

[0022] Further suitable active substance ingredients according to theinvention are descaling active substance phases, preferably acidicdescaling active substance phases. Such descaling active substancephases can contain, apart from the actual descaler—this is preferably anorganic or anorganic acid—and water, optionally further ingredients suchas surfactants or emulsifiers, thickeners, aromatics, preservatives,etc.

[0023] It is equally possible to use, as active substance fluids, highlyconcentrated surfactant phases, so-termed “foam boosters”. Such highlyconcentrated surfactant phases can contain, apart from the surfactants,also further usual ingredients.

[0024] According to the invention active substance fluids with anantibacterial and/or fungicidal and/or antiviral active substance phaseare equally suitable, wherein the active substance phase can contain,apart from the active substance acting antibacterially and/orfungicidally and/or antivirally and water, optionally furtheringredients such as, for example, surfactants or emulsifiers,thickeners, aromatics, preservatives, etc.

[0025] In addition, it is possible for the active substance fluids to beactive substance phases with an enzyme content. Such active substancephases with enzyme content can contain, apart from the enzyme or enzymesand water, optionally further ingredients such as surfactants oremulsifiers, thickeners, aromatics, preservatives, etc.

[0026] Equally, it is possible for the active substance fluids used inaccordance with the invention to be absorbent, particularlyodour-absorbent, active substance phases. These can contain, apart fromthe absorption agent, particularly an odour-absorption agent, and water,optionally further ingredients such as surfactants or emulsifiers,thickeners, aromatics, preservatives, etc.

[0027] The dispensing device according to the invention offers, inaccordance with a special embodiment, the possibility of usingcombinations of different active substance fluids in the storagecontainers 2, 3, wherein according to a preferred embodiment one of thestorage containers 2, 3 contains an aromatic phase, particularly aspreviously defined.

[0028] Examples of active substance fluid combinations to be used areperfumed aromatic phase combined with chlorine bleach (not stable instorage together with one another), perfumed aromatic phase with highlyconcentrated surfactant phase (foam booster), aromatic phase withdescaling acidic active substance phase, aromatic phase withantibacterial active substance phase, different acid systems, aromaticphase combined with active substance phase having an enzyme content,perfumed acid phase combined with watercolouring phase, aromatic phasewith odour-absorbent phase, perfumed acid phase with available oxygen,perfumed acid phase with active substance phase, thickened withpolyacrylate, etc. Of particular interest in that case are viscous togel-like active substance fluids with viscosities in the region of a fewthousand mPas, particularly 2000 to 5000 mPas, preferably 2500 to 3500mPas (measured by Rotovisko LVT, hydrometer 2, 6 rpm, 200° C.).

[0029] In the case of the illustrated dispensing device each storagecontainer 2, 3 has an own outlet opening 4 by way of which therespective active substance fluid can be dispensed into the flushingliquid. By contrast to the state of the art forming the starting pointfor the teaching, it is now the case here that the storage containers 2,3 are protected against entry of flushing liquid into the interiorthereof. The outlet openings 4 of the storage containers 2, 3 are thenso arranged that only active substance fluid issues. The dispensing of apartial quantity of the active substance fluid from each of the storagecontainers 2, 3 into the flushing liquid takes place in each flushingprocess. In the illustrated embodiment this is realised by the fact thatthe outlet opening 4 of the respective storage container 2, 3 in usesetting, thus as illustrated in FIG. 2, is arranged at the base.Flushing water flowing over always impinges laterally on the storagecontainers 2, 3.

[0030] Many different possibilities exist for the arrangement andmounting of the storage containers 2, 3 at the holder 1. In theembodiment which to that extent is preferred and is illustrated in thedrawing it is provided that the storage containers 2, 3 are mounted ormountable in the container 1 to be individually exchangeable. Analternative consists in coupling the storage containers 2, 3 together bymeans of an adapter or the like and mounting them, thus coupled, in theholder 1. A further alternative consists in directly coupling thestorage containers 2, 3 together and mounting them, thus directlycoupled, in the holder 1. Finally, it is also conceivable to constructthe storage containers 2, 3 in a common unitary housing, for example asseparate chambers in a cohesive housing, and then mount them in thatform at the holder 1. One or other variant can be selected according topreferences in practice and the active substance fluids to be used.

[0031] The storage containers 2, 3 can be designed, as described in thestate of the art (DE 299 02 066 U1, DE 199 15 322 A1), to each beindividually refillable by way of a refilling opening optionallyequipped with a valve. In particular, in this case the storagecontainers 2, 3 can also be fixedly mounted or constructed in thecontainer 1, thus a unitary arrangement closed in itself can beselected.

[0032] The illustrated embodiment, however, shows the storage containers2, 3 as exchangeable single-use containers which will be very widespreadin practice. The illustrated and preferred embodiment shows the storagecontainers 2, 3 arranged adjacent to one another at the holder 1. Thesame applies to an arrangement of the storage containers 2, 3 one behindthe other. Alternatively, it could also be provided to arrange thestorage containers 2, 3 one above the other for the purpose of productdelivery in cascade manner.

[0033] The illustrated and preferred embodiment further shows that thestorage containers 2, 3, which here are, in fact, individuallyexchangeable, can be mounted in the container 1 by plugging in fromabove (into use setting). Diverse other possibilities of fastening comeinto question as alternatives. For example, it could be conceivable topush the storage containers 2, 3 into the holder 1 from the side. Itcould also be conceivable to place the storage containers 2, 3 laterallyat the holder 1 and then pivot into the use setting about a pivot axis.One or other variant can be selected according to the respectiveconstruction of the outlet openings 4 and the method of closure thereof.

[0034] In principle, it is possible to use as active substance fluid,for example, gels with very high viscosity or pastes which are notindependently capable of flowing. In this case it can be recommended forthe storage container 2, 3 to have a flexible wall portion or a flexiblewall overall and an expulsion of the active substance fluid disposedtherein takes place by pressure loading of the storage container 2, 3.This pressure loading can be exerted by way of, for example, anappropriate mechanism via the flushing liquid which flows over.

[0035] It has already been mentioned above that in the case of themulti-chamber dispensing device according to the invention dispensingmechanisms can, in principle, be used which are known from the state ofthe art for dispensing devices for a single active substance fluid. Tothat extent a constructional possibility, which generally speaking goesback to EP 0 538 957 B1, applicable in the present case is that aplate-shaped distribution element is provided at the holder 1 and has aloading region flowed over by flushing liquid during the flushingprocess, wherein the interior of the storage container 2, 3 is disposedin permanent connection with the distribution element by way of theoutlet opening 4, optionally with interposition of an arrangementpreventing free flowing of the active substance fluid. According to aparticularly preferred embodiment the plate-shaped distribution elementis associated in common with all storage containers 2, 3.

[0036] The illustrated and preferred embodiment depicts a solutionoperating with an actively closing sealing element. Here the outletopening 4, which is arranged at the base, of the storage container 2, 3is closed by means of, in particular, a sealing element 5. The sealingelement 5 is biased into the closed setting closing the outlet opening 4and is displaceable against the biasing force into a release settingslightly freeing the outlet opening 4.

[0037] For displacing the sealing element 5 there is provided anactuating element 6 which cooperates with the sealing element 5 andwhich is transiently loaded by a force via the flushing liquid in eachflushing process to such an extent that the sealing element 5temporarily adopts the release setting against the biasing force. Forthat purpose a loading region 7 which is acted on by flushing liquidduring the flushing process and on which the flushing liquid thusimpinges during the flushing process is disposed at the actuatingelement 6. The actuating element 6 is constructed as a single-arm leverpivotably connected at one end with the holder 1. The sealing element 5is arranged at the actuating element 6 at a specific spacing from theloading region 7. Due to the single-arm construction of the leverforming the actuating element 6 (FIG. 3) the effective direction of theforce exerted by the flushing liquid is aligned with the direction ofopening of the sealing element 5. The sealing element 5 can thereby belifted from below from the outlet opening 4 of the storage container 2,3. It is thus possible without further measures to exchangeably mountthe storage container 2, 3 without special constructional features.

[0038] In the illustrated embodiment the sealing element 5 is arrangedbetween the end, which is pivotably connected with the holder 1, of theactuating element 6 and the loading region 7. The opening path of thesealing element 5 is thus comparatively small and opening takes place,as desired, with only a quite small gap. Moreover, this gap is, withappropriate design of the sealing element 5, opened asymmetrically,namely opening more strongly in the direction of the loading region 7 sothat the effective substance fluid preferentially issues in thisdirection. That is the direction for the flushing liquid, with which theeffective substance fluid then appropriately mixes. The effectivesubstance fluid can thus run on the upper side of the actuating element6 in the direction of the loading region 7 and already mixes on thispath with the flushing liquid which flows over.

[0039] It is possible to provide for the sealing element 5 to beintegrally formed at the actuating element 6. This is recommendedparticularly in the case of design of the actuating element 6 from aplastic material, particularly from plastic material capable ofinjection moulding. In addition, the holder 1 can, in particularlypreferred manner, consist of plastic material, especially a plasticmaterial capable of injection moulding, preferably thermoplasticsynthetic material. Overall, it can be provided that the actuatingelement 6 is integrally formed at the holder 1 and the biasing force isproduced by the inherent resilience of the actuating element 6.

[0040] The illustrated and preferred embodiment is now distinguished inparticular manner by the fact that the actuating element 6 is associatedin common with the sealing elements 5 for at least two storagecontainers 2, 3, preferably for all storage containers 2, 3. There canbe recognised in FIG. 1 in plan view the wide actuating element 6, whichis of plate-shaped construction, with the equally wide, pan-shapedloading region 7 and the small outflow openings 8 recognisable therein,all in the frame-shaped base plate 9 of the holder 1. The arrangement ofthe outlet openings 4 at the storage containers 2, 3 is matched thereto.In particular, these containers are, with respect to the centre of theoverall dispensing device, constructed asymmetrically with outletopenings 4 offset relative to the centre of the dispensing deviceoverall (FIG. 2). There is thereby obtained a concentration of theactive substance exit at a relatively narrowly defined region regardlessof the fact that two storage containers 2, 3 are provided.

[0041] Finally, a dispensing, which is controlled in specific manner, ofactive substance fluid from the different storage containers 2, 3 can berealised in the manner that the flow cross-sections at the outletopenings 4 and/or at the sealing elements 5 are able to be determinedand/or set to be different.

[0042] Finally, there are a number of design possibilities of theillustrated dispensing device in constructional respects, particularlywith regard to the arrangement and formation of the outlet openings andsealing elements. In this connection, there is a contemporaneously filedparallel patent application of the applicant, to the disclosure contentof which reference may be made (DE . . . ). In particular, asimultaneous metering or a metering delayed in time can be realised withthe same or different concentration from the different storagecontainers.

[0043] The present invention is further explained by reference to thefollowing examples, which do not, however, restrict the invention in anymanner. Different active substance fluid combinations for the storagecontainers 2, 3 of the dispensing device according to the invention aredescribed in the examples.
